SYRUPER.

Specification of Letters Patent.

Patented Sept. 9, 1 913.

To all whom it may concern Be it known that we, WILLIAM C. ANDER- SON and ALBERT R. THOMPSON, citizens of the United States, residing at San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Syrupers, of which the following is a specification.

Our invention relates to the class of cansyruping machines, or, as they are commonly known in the art, syrupers.

Our invention is especially intended for the syruping of open topped cans, and it embodies andincludes provisions for holding the fruit down in the cans while the syrup is being supplied, and for insuring, by a proper disposition of any excess of syrup, the exact amount of syrup remaining in the cans, without regard to the volume supplied.

These are the objects of our invention and they are attained, briefly stated, by swinging perforated presser caps adapted to timely cover the cans and hold the fruit in while the syrup is passing through said caps into the cans; and by means for tilting the cans as they enter and pass through the machine, so that the excess of syrup will overflow the can rims and thus provide for a given level in said cans when they again assume an upright position.

In these means, together with novel details of construction, adjustment, arrangement and combination, our invention consists as will be more fully explained and ululerstood by reference to the accompanying drawings in whielr- Figure 1 is a plan view of our syruper. Fig. 2 is avertical sectional view oi? the same.

1 are the supporting legs to which is bolted a drip pan 2, which is to receive the excess of syrup spilled from the cans.

1: a non-rotatable centrally disposed post to which the non-rotatable parts are fixed, and upon which the rotatable parts are mounted and turn.

4- is a sprocket the hub 5 of which is journaled on the post This sprocket is formed or provided with an annular upris' ing flange 6. i a

7, in Fig. l, is the inleading track and S the outleading track.

9 is a traveling carrier chain which leads in over track 7, engages and semi-circles the sprocket 4 and leads out over track 8, thereby rotating said sproekct. This carrier chain 9 has its articulated links disposed vertically or on edge, and certain ones of said links, at suitably spaced intervals, are provided or formed with flights 10, which in their course around the sprocket 4-, overlie on one side the outer portion of the sprocket surface and on the other side they rest upon a steadying track 11, which rises from the rim of the drip-pan 2, the surface of said track being higher than the surface of the sprocket. The cans 12, rest upon the vertically disposed links of the carrier chain 9 between the [lights 10 thereof, and are carried to the rim of the sprocket where their bases overlie both said rim and the track 11.

13 is a can-tilting plate inclining centrally, its upper portion on its inner side being formed or provided with a rail 14:. The functional part of the can-tilting plate 13 encircles one-half the machine, but at its ends it has tangential extensions 13' to furnish safe guides for the entering cans.

it will now be seen that as a given can reaches the beginning of the tilting rail 14, said can will be til-ted over inwardly until the inner side of its base rests upon the surface oi. the sprocket, as shown in Fig. 2, and it will be held at this angle until it reaches the other side of the machine, Where passing from the rail i l, it will return to an upright position, being so placed, as is shown, as to be over-weighted outwardly.

The cans 19 being of the open-topped type, without aps, require some means to hold the fruit down while the can is tilted and the syrup is being supplied. For this purpose we provide the holding pressurecaps 15. These caps are adapted to fit down upon and cover the tops of? the cans. They are perforated as shown at 16, in Fig. l, to admit the syrup, while confining the fruit; and on their inner sides the under surface of the caps is grooved as shown at 15 in Fig. 2, to allow the syrup to spill out. The caps have a flange 1,7 to properly direct the entering syrup. These prcsser caps 15 are carried by arms l3, pivoted at 19 to an annular bracket 20, the hub 21 of which is fitted upon the hub oi the sprocket 4i and rotates therewith. Behind their pivotal points at 19, the arms 18 are extended and have their extremities 92 engaging the groove of a cam 23 fixed on the non-rotatable post 3. This cam 23 has its groove on two levels, as shown in Fig. 2, the higher level acting to force the presser cap 15 down upon the can, and the lower one serving to lift the cap from the can. Rotatably mounted upon the upper end of the post 3 is a hollow distributing head 24 from which radiate pipes 25 fitted with down-turned filling ends 26. In each filling end is a controlling valve 27.

28 is a pipe leading from the source of syrup supply. This pipe leads into the hollow head 24 through a suitable stufiing box.

29 are bracket arms which at their outer ends are fitted on the filling ends 26 of the pipes 25, and at theirinner ends are bolted to the annular bracket 20, this connection being for the purpose of rotating the pipe system in unison with the other rotating parts. I

The valves 27 are of any suitable type. They are automatically opened and closed by the following mechanism. Each valve 27 has an operating handle 30, which at. its inner extremity is provided with a downturned stud 31. Fixed upon the central post 3 is a plate 32, which has a groove 33, said groove being concentric with but inside of the circular path of travel of the handle studs 31 when said handles are in position to keep the valves closed. On the plate 32' is a gate 34 which is pivoted at 35 and is adapted to swing outwardto intersect the path of travel of said stud 31 when the valve is closed, as is shown in Fig. 1. The free end of the gate 34 is connected by a link 36 with a crank 37 on a turnable' spindle 38 passing up through the hollow of the central post 3, said crank emerging through and playing in a slot in said post. A spring 39 connected with the gate, as shown in Fig. 1, holds it normally in outofwthe path of travel of the stud 31."

40, (indicated in dotted linesin Fig. 1)

is a turnable shaft, the upper end of which carries an arm 41, which normally lies in the path of that can 12 which is about to enter the machine. Thelower end of the shaft 40 has a crank41' which is connected by a'link 42 with'a crank'43 on the lower end of the spindle 38. When the can 12, Y which "is just entering the machine, comes in,

contact with the arm 41, it willcause the shaft 40 toturn, and this movement through the cranks 41 and 43 and rod 42 will turn 'thespindle 38. The turning of this spindle,

' through its upper crank 37 and link 36 will 7 swing the gate 34 outward across the path of the stud 31. When this stud, therefore, comes 'in contact with the gate 34, said stud and its valve handle will be forced inward and will thence-forward travel in this posistud 31 and the valve handle outa ain thereby closing the valve and cuttingo the supply of syrup. If there should be no can entering the machine, the gate 34 will re main inits normal position and the stud 31 will not be forced in, and the valve of that pipe will not, therefore, be opened. The closing cam 32 is fitted by means of bolts 33 in the groove 33, so that said cam may be set in any position on the plate in order to close the valve at any desired time, pre viously determined upon. Now, in order to make provision for varying the angle at which the can is tilted while being supplied with syrup, so that the machine may. be suited to the ideas of diiferent users with respect to the amount of syrup it should contain, we call attention to the following adustments.

In the flange 6 of the sprocket 4 are seated stop screws 44 which bear on the cans. By setting these in, the cans will be permitted to tilt to the least angle; by setting the screwsout, the cans will tilt to a greater angle. Thus any angle may be chosen, and the amount of syrup retained in the cans may be regulated to suit the user. As provision is thus made to vary the tilting angle of thecans, it is obvious that provision must I also be made for the adjustment of the presser-caps and their operating cam, in order to conform to the altered angle of the cans. This we accomplish by making the fitting between the hub 21 of the annular. bracket 20 which carries the presser caps,

and the hub 5 of the sprocket 4 a slip joint,

so that the bracket may be raised or lowered and may be fixed in position by a set screw 45. In like manner the presser-cap cam'23 is made vertically adjustable on the central post 3, and is, fixed by a set screw- 46.

Finally as the annular bracket 20 is adjust able vertically, and as the connected pipe system will move with it, we make the valveoperating plate 32 also vertically adjustable The operation of, the machine is as follows z-The open-topped cans 12 filled with fruit are carried in continuous succession into the machine by the carrier chain 9. This chain is also the driving mechanism of the machine and through the sprocket '4 all the moving parts arerotated about the central post 3. As the first can reaches the tilting rail 14 itis tilted inward to the angle previously determined upon by the adjustment of the stop screws 44. At'the same time, the overlying presser cap 15 descends upon the topof the can and holds thefruit in. Also at" the same time, the can, by contact with the arm 41 efiects, through the connections described, the outward swing of the gate 34, so that the stud 31 of the valve handle 30 and fix it with a set screw 47.

valve 27 of the overlying syrup supply pipe.

The syrup now flows down through the perforated presser-cap into the can. This continues until the can is near'the other side of the machine, when the excess of syrup spills over the rim of the tilted can through the grooves 15' of the presser cap, and'thus leaves the can with only the amount of being free of the tilting rail, will resume its upright position and be carried out of the machine. Succeeding cans are subjected to like operations, and the work is continuous. 1
